Learn This article will help you learn parameter definition strategies for creating the most efficient set of TCD tests.

Long lists of Values always result in large numbers of tests

Reason:

• Imagine you are testing an application that has a drop box with 500 city names
• The application also has 5 different features that will be tested together with different cities
• If you list each city individually and create a set of 2-way tests, the smallest possible number of tests you would generate would be 500 X 5 = 2,500 tests

Instead, define Equivalence Classes and enter them into Test Case Designer

Depending upon the business rules and behaviors of the application you are testing, you might break your equvalence classes of cities into size-based categories or location-based categories such as these:

...

If you reduced your list of city-related Values from 500 to 4, you would have far, far fewer pairwise tests generated when you click on the Test Cases Scenarios button.
